About the vegan honey-mustard recipe

This roasted veggie and grain salad is perfect for fall and winter, but if you switch up the vegetables, you can eat it all year long. The star of the dish? A tangy, sweet maple mustard dressing that doubles as a salad dressing or dipping sauce.

Why This Dressing?

Traditional honey mustard isn’t vegan, but this version swaps honey for maple syrup, making it 100% plant-based. It’s easy to make, keeps well in the fridge for over a week, and pairs with everything.

Ingredients

  • Dijon mustard (or yellow mustard for a milder taste)
  • Maple syrup (or agave, vegan honey alternative, or any liquid sweetener, even honey if you are not vegan)
  • Rice vinegar (or white wine vinegar—any mild vinegar works)
  • Extra virgin olive oil (or water for an oil-free version)
  • Salt and freshly ground black pepper

How to Make the Maple Mustard Dressing

  1. Mix mustard and vinegar in a bowl.
  2. Stir in maple syrup and olive oil until combined.
  3. Season with salt and pepper. Adjust to taste.

How to Use This Dressing

  • Drizzle over roasted vegetables or salads.
  • Use as a dip for veggies or vegan nuggets.
  • Spread on burgers or sandwiches.

Best Greens for Fall & Winter Salads

Kale and red cabbage work well because they hold up to warm grains and roasted veggies without wilting too much.

Roasting Vegetables Perfectly

  • Cut veggies into uniform sizes for even roasting.
  • If using vegetables with different cooking times (e.g., potatoes and asparagus), roast them on separate baking sheets. I like to use quarter pan sheets.
  • Check for doneness and remove veggies as needed.

Storage Tips

  • The dressing can be doubled or tripled.
  • Store in an airtight container in the fridge (it doesn’t freeze well).

Variations

  • Swap farro for quinoa or brown rice.
  • Use butternut squash, delicata squash, or your favorite roasted veggies.
  • Top with hazelnuts, walnuts, pecans, or almonds. Or even with a savory granola.
  • Add your favorite legume like lentils or chickpeas
  • Not vegan: add rotisserie chicken chopped or shredded.

How to Make This Salad Even Easier

This salad is already simple, but here are a few shortcuts to make it even faster:

1. Use Pre-Chopped Vegetables

Save time by buying pre-cut veggies from the grocery store. Many stores offer pre-diced sweet potatoes, butternut squash, or even a mix of root vegetables ready to roast.

2. Go for Frozen

Frozen vegetables work just as well! Trader Joe’s and other stores carry pre-roasted frozen sweet potatoes, butternut squash, and even cooked grains like quinoa and brown rice. Just heat and toss them into the salad.

3. Batch Cook Grains

Cook a big batch of farro, quinoa, or brown rice ahead of time and store it in the fridge or freezer. That way, you can assemble the salad in minutes.

4. Swap Nuts Based on What You Have

No hazelnuts? No problem! Use whatever nuts or seeds you have—walnuts, pecans, almonds, pine nuts, or even pumpkin seeds for a crunch.

5. Eat It Warm

If cold salads aren’t your thing in the cooler months, serve this one warm! The roasted veggies and grains make it hearty and satisfying even on chilly days.

With these shortcuts, you can whip up this delicious salad quickly. Enjoy it with minimal effort and maximum flavor!
